Here is a character from the Cathar Juhani's side-quest. This is the last side-quest that players can take on in the game.
Xor: a male Twi'lek Mandalorian slaver, who fought in the Battle of Cathar prior to the Mandalorian Wars.
Over the years, Xor searched for Juhani and her family. He eventually caught up to her and attempted to buy her. The Jedi led by Revan freed Juhani from enslavement. Xor was bested, but would search again until his prize was restored.
Right at the time of the Jedi Civil War, Xor found Juhani and promised to enslave her the next time they met. When Xor met Juhani again, Xor and his two cronies attacked the Cathar and her companions. Juhani overcame the dark side, staying in the light. Xor succumbed to his wounds and died, with no reward.
